Were there ever any SMD controller cards for the PC? Add me to the list of those wishing to read data from old SMD disks...

Does anyone have a datasheet for the TI or Cyrix 486slc/e CPU? I need to find a pinout for one of these, all I have been able to locate is the pinout for the 386sx - this gives me most of the info I need but the 'unused' pins of the 386 sx were used for cache and power management on the 486slc...
